flattening. The chief peculiarity of this species resides in the 

 abnormal outline and medial impression of the eleventh antenual 

 joint ; it may be placed near /buezcornis in the lists. 



B. scltmitti n. sp. — Eather strongly ventricose, polished, impunctate, 

 piceous-black throughout, the legs somewhat paler, the antennal club pale ; 

 pubescence rather abundant, pale in color, long, suberect and bristling. ITead 

 large, wider than long, very much wider than the prothorax, the eyes rather 

 small but convex and prominent, at distinctly more than their own length 

 from the base, the tempora behind them very rapidly convergent and circularly 

 arcuate to the neck ; fovese only moderate in size, near basal third, pubescent, 

 widely separated, united by a rather narrow but deep, entire and semicircular 

 ambient sulcus, the enclosed surface strongly convex, perfectly smooth and 

 polished, with a short central carina ; supra- orbital carinse feeble ; surface ex- 

 terior and anterior to the sulcus flattened, horizontal and coarsely, densely 

 punctato-rugose, the frontal margin broadly and obtusely subangulate ; viewed 

 anteriorly, this margin is feebly double, the intervening concavity very slight 

 and obliterated at the middle, the lower edge thinner, more acute, briefly 

 porrect and feebly and minutely sinuate at each side of the middle ; clypeus 

 rather abbreviated, very broadly subtruncate, with an entire double edge at 

 apex, the middle jjoint of the upper edge bearing an obliquely erect liguli- 

 form process arising just before the middle of the frontal edge ; excavation be- 

 tween the clypeus and front extremely deep, the clypeus sparsely studded with 

 short setae, the lower frontal edge bristling with longer setae directed down- 

 ward. Antennie slightly longer than the head and prothorax, stout, the club 

 very strong; basal joint extremely large, inflated acd subcompressed beneath, 

 the flattened inner surface minutely and densely pubescent ; second joint 

 small, quadrate, attached to the outer side of the apex of the first at nearly 

 right angles with the axis, only slightly stouter and longer than the third ; 

 three to eight equal in width, closely joined, slightly transverse ; ninth shorter 

 and distinctly wider, strongly transverse ; tenth large and subglobose, as wide 

 as the eleventh, nearly as long as wide, almost its entire under surface occu- 

 pied by a very large and deep excavation, the inner slope of which has a large 

 and deeper perforation clothed with short radiating setse; eleventh about as 

 long as the three preceding combined, obliquely pointed at tip. Prothorax rela- 

 tively small, scarcely as long as wide, the sides broadly rounded anteriorly, 

 moderately convergent and but feebly sinuate behind the middle ; marginal 

 liairs in the form of long stiff close-set and posteriorly arcuate setse; disk with 

 two large sublateral fovese near the base, connected to the median and more 

 basal fovea by shallow arcuate sulci each before a stout spiniform process ; 

 lateral and median sulci very deep and almost entire ; intermediate carinse 

 strong but shorter, the lateral sulci turned outward near the apex, and here, 

 at each side of the middle, there is a small deep fovea. Elytra % longer and 

 fully % wider than the prothorax, not quite as long as wide, the sides moder- 

 ately divergent from the very large, prominent and obtusely angulate but not 

 spinose humeral plicae to the apex and broadly arcuate ; surface convex ; three
